Why don’t they go and pick on the Lutherans? They are practically Catholic.
AFAIK Lutherans ignore them. Their religion demands attention, it’s me me me me all the time. They cannot handle being ignored.
Who knows. Certainly not out of any fealty to Luther who was too Catholic for these individualist churches anyway.
Perhaps it’s because the Church is hierarchical more so than Lutheranism; the key fundamental doctrine these posters share is individualism, “it is what i say it is.’ [I being what I say scripture means.] And also because the Church is so much bigger than Lutheranism.
Size and authority is my guess. Grates against the ego most of all.
